The player(s) is presented a three dimensional view at the arena. There is a white divider in the middle, or possibly the net. The player one's paddle is a red square, the player two has a blue paddle. The current score is displayed in the upper left corner. The ball is a green diamond, and dark green markers follow the ball on the walls to display it's position in relation to them.

The player(s) controls a paddle at one end of the arena with mouse movement. To serve, the player presses the mouse button three. The key c toggles whether the player needs to keep the mouse button one pressed while dragging the mouse. See also the --noclickn switches below.
